The Welsh teacher, who had gone without sex for 13 weeks, quickly made up for lost time.

She jumped between the sheets with her beefy lover of four years.

And hotel staff even laid on a pile of grapes – the babe’s favourite treat – for her to nibble.

But despite her bedtime treat, Rachel woke up frazzled. And now friends and family are worried about her health.

Last night a pal of Rachel – who scooped £100,000 by winning the show – said: “She’s in a state of total shock. Her family are with her and are trying to help her come to terms with it all. But it’s proving really tough.

“She can’t handle it. Everyone is very concerned that winning could be a real nightmare for her.

“It’s almost like a trauma rather than a great moment. She even had to be persuaded to go to the end-of-series party.”

The Daily Star Sunday spoke to Rachel before she ran for cover with her family.

They dragged her to a hairdresser’s in a desperate bid to give her a cheering makeover ahead of the get-together with her co-stars.

And in a bid to shake off her dowdy image Rachel, 24, revealed she planned to marry Richard – and show off her naughty side.

She wants to ditch her “Plain Jane” persona and strip off for a nude photoshoot.

Rachel said: “I would love to do a sexy photoshoot. I don’t think I’d get my boobs out unless it was for charity and done very classily, like the black and white ones the celebrities do. But yes, I would consider it.”

Rachel, who won the closest-ever final when she beat blind Mikey Hughes by just 2% of the vote, said she couldn’t wait to walk down the aisle with Richard after watching Mario and Lisa’s romantic proposal.

“I wouldn’t have had sex in the house but I can’t wait to make up for lost time! It’s going to be great. If I could get married tomorrow, I would,” she said.

“Richard is definitely The One. He’s a very nice, kind, genuine guy.

“He respects people and is very sweet. If you met him, you would know what I mean. I’m a very, very lucky girl.

“I would have loved to have him in the house with me, like Rex had Nicole and Lisa had Mario.

“I don’t think he would have liked it but I would have loved to have given him a big hug and squeeze.”

The Welsh lass dropped an amazing four dress sizes – from a 16 to an eight – before entering the house because she was paranoid about her size.

And she was terrified she’d pile on the pounds in the house, bringing back bad memories of her “Thunder Thighs” nickname.

Rachel moaned: “I was worried I was going to put on weight in the house. I knew it could be a problem when I went in, so I took in a skipping rope and ran round the garden.

“When you are fit you can get yourself in shape after about a month of training. So I can’t wait to get back to the gym.”

The kind-hearted champion is now planning to donate £10,000 of her £100,000 prize to charity.

She said: “I’m going to split £10,000 of the prize money between five different charities.

“One of them will definitely be the Stroke Association, another will be for cancer and the third will probably be Save The Children. But I will have to think about the other two.

“As for the rest I have a few debts that need to be cleared from being a student and I would love to have a car that doesn’t break down every time I go round a roundabout.”

Despite winning, Rachel has faced a bitter backlash from furious fans and fellow contestants who branded her too boring to be crowned champion. Out of all the 19 housemates who appeared on the final night, only Kat and Mikey thought she was a deserved winner.

One insider claimed Rachel winning the ninth series was the show’s biggest anti-climax since Cameron Stout won BB4.

The source said: “Rachel proved she was genuinely a nice girl and not playing a game as people thought.

“But it would have been much better for Big Brother if one of the other finalists had won.”

Surprisingly, Rachel admitted she was boring – but said she was not going to change for other people.

She added: “People said to my face that I was boring but it didn’t really affect me because I am confident with the person that I am. Maybe I am boring, who knows?”
